How to Adjust the Picture on a Zenith Projection Screen

Save

Zenith rear-projection televisions have evolved as new technologies are developed, improving both the way the picture is created and the interfaces available for connecting to video source components offering HD video and digital audio. One major change was from the use of cathode ray tubes (CRT) to digital light processing (DLP) to form the picture and color. Regardless of the exact technology used, the method for adjusting and improving the picture you see has been largely unchanged.

  • Press "Menu" on your Zenith remote control to open the on-screen menu. Press the up or down arrow key to select the "Video" menu, and press "Enter" or the right arrow button to access the video menu.

  • Press the up or down arrow button to select an aspect of the picture you wish to adjust, such as the contrast, brightness, color, tint or color temperature (enhances the red for a "warm" picture or the blues for a "cool" one). Press the left or right arrow button to make an adjustment of that aspect.

  • Press the "Video" or "EZ Video" button if your remote offers this feature, or select the "EZ Video" (or "EZ Picture") option in the Video menu to select one of the preset picture modes, designed to optimize viewing with particular sources or conditions. Preset options vary by model, and will include settings for "Daylight," "Movie" and "Sports," or "Clear," "Optimum" and "Soft."

  • Press the "Ratio" button (or "ARC" with some models) to adjust the aspect ratio of the picture. Options will include a standard 4:3 screen size, a 16:9 widescreen size and others including "Zoom" and "Horizon."

  • Select the "Convergence" option in the Video menu (with Zenith CRT projection TVs) to align the three picture tubes (red, blue and green) if your screen is showing a discoloration or "rainbow effect." Select the automatic adjustment mode if you choose, or adjust manually by selecting the all-point adjustment ("1+") or individual point ("9+") and using the numeric keypad to select a point to adjust. Use the arrow keys to align the red or blue cursor on the screen with the green cursor. When all three are aligned, the cursor will turn white. Press "Exit" when finished.

  • Select "Video Reset" in the "Video" menu, if your model offers this option, to restore the picture to its original factory settings.

Tips & Warnings

  • Consult your owner's manual for more detailed information on the specific picture options available with your model.
  • Let your TV run a minimum of 20 minutes before initiating the convergence adjustment feature.
